Sol Associates

Romanian renewables execution

Romania has the projects. It needs contractors who can build them.

For EPC contractors entering Romania, Romanian contractors entering renewables, and solar and storage builders moving into wind: the market evidence, the entry routes and the package-level know-how, from someone who spent a decade selling turbines, developing wind farms and negotiating projects, and now advises investors and developers.

Three ways in

Which contractor are you?

Each route has a different first package, a different qualification gap and a different reason to lose money. Pick yours.

Route 01

International EPC entering Romania

  • Legal presence, ANRE attestation and local partners before the first bid
  • Which projects are buildable now, not just permitted on paper
  • Bonding, payment security and FIDIC practice in the local market
Open the playbook → Route 02

Romanian contractor entering renewables

  • Turn civil, electrical or industrial capability into a renewables package
  • Developer, lender and owner’s-engineer expectations
  • Getting on the bid list at the right project stage
Open the playbook → Route 03

Solar or storage EPC moving into wind

  • What really changes: OEM interface, heavy lift, foundations, oversize logistics
  • The balance-of-plant packages where your skills transfer first
  • Hybridisation of existing wind sites as a bridge

The build-out

The plan needs roughly 2.8 GW of wind, 3.5 GW of utility solar and 1.9 GW of storage in five years

Romania’s installed wind fleet barely moved for a decade, at about 3 GW. The national energy and climate plan trajectory almost doubles it by 2030, while storage goes from a rounding error to around 2 GW. That is a construction programme, and construction programmes run on contractors, crews, cranes and bonding capacity.

The trajectory is a policy path, not a forecast of what will be built.

Where the work is

14.0 GW of wind sits in the grid-connection pipeline, and 92% of it is in the east

Sol’s reconciled grid-connection register joins 26,602 project records from the Transelectrica connection registers, the ANRE licence and authorisation lists and the April 2026 government stage list. Wind concentrates in twelve eastern counties (Constanța, Tulcea, Galați, Brăila, Buzău, Vaslui, Iași, Ialomița, Călărași, Bacău, Vrancea, Botoșani), led by Constanța, Galați, Tulcea and Vaslui.

The certified electrical contractors do not. Of the 541 firms holding ANRE attestation classes D1, D2, E1 or E2 in our September 2026 extract, 35% are registered in Bucharest and Ilfov and only 13% across those twelve eastern counties. That gap is the opening.

Mixed observation dates. Register presence is not finance, construction readiness or an open tender. Registered office is not where a firm can work.

Why more projects are adding batteries

Midday power was worth a third of the evening peak in 2025

Across 2025, the Romanian day-ahead price averaged EUR 59/MWh at 14:00 and EUR 183/MWh at 20:00, with 196 negative-price hours between March and September. Owners respond by adding batteries to solar and wind sites. For a contractor this means battery integration, power-conversion and grid-compliance skills are increasingly part of many packages, including wind.

Who you would be working with

A decade of turbines, development and deals

Radu Voinescu leads Sol Associates. Before advising investors and developers, he sold and contracted wind turbines for two leading turbine manufacturers, ran a developer’s Romanian platform, and structured the acquisitions that come before every EPC tender.
